JOSEPH D. MULLEN, OF ST. LOUIS, 'MISSOURL ASSIGNOR TO TEXAS DELINTER COM- PANY, LIMITED, OF SHREVEPORT, LOUISIANA, A CORPORATION OF LOUSXANA.

DELINTER.

To all LU/wm t may concern.

Be it known that I, llosiiPi-i D. lllULLiiN, a citizen of the United States, residing at the city of St. Louis and State of Missouri, have invented certain new and useful `improvements in Delinters, (Case 15,) of which the following is a specification.

This invention relates to eottoii-seed delinters` and has for its object to provide novel improvements in the machine which constitutes the subject-matter of another application tiled by me of even date.

lith this object in view, the present invention consists of the novel features of construction and arrangement of parts, as will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings forming part of this specification, in which like numbers of reference denote like parts wherever they occur, Figure 1 is a longitudinal sectional view of a delinter embodying the present invention; Fig. 2 is an end elevation of same; and Fig, 3 is a sectional view on the line 3 3, Fig. 1.

The casing 1 contains the delinting` mechanism, and is supported by standards 2 which may be supported on a suitable base 3. The ends of the casing 1 are closed by heads or castings 4, which may be supported on standards 2, and the top of said casing is closed by a cover plate or a plurality of such cover plates, which may be detachably secured in place by any suitable means, so that either one or all of said plates may be removed, in order, to permit ready access to the interior of the machine for the purpose of cleaning or repairing same or for any other purpose. The bottom of said casing 1 is preferably hopper-shaped and is provided with an outlet 6 which is controlled by a gate or valve 7 of any suitable construction, the purpose of said outlet being to allow any seeds that may fall into the bottom of said casing to be removed, when gate 7 is opened. A suction pipe 8, connected to the lower part of the casing l, is adapted to draw the lint from'the interior of said easing and is connected with any suitable source o-f suction supply (not shown).

The delinting cylinders 9 are preferably arranged so that their axes of rotation are substantially horizontal within the casing 1, the shafts 10, which support said cylinders, being journaled in openings in the heads t.

Said cylinders 9 are preferably spaced apart symmetrically, and between each two adjacent cylinders a stationary stave 11 is located, the purpose of this arrangement being to form a delinting chamber 12, the walls of which are the delinting cylinders 9 and the staves 1l. Each cylinder 9 is preferably formed of a metal tube which is screwthreaded externally and the ends of said cyliiider are secured to suitable heads 13 which are rigidly mounted on its supporting shaft l0, the periphery of the screw-threads being serrated, so as to form teeth 14 which are adapted to remove the lint and fibers from the seeds that come in contact with said cylinder. The screw-threads are preferably formed with a relatively large pitch and the cylinders 9 are rotated in such direction that the screw-threads thereon will have a tendency to feed. the seeds from the receiving end to the discharge end of the delintiiig chamber.

it one end of the machine, each shaft 1() projects from the head 4t and bears a gear 15. A wheel 1G on drive shaft 17, which receives its power from any suitable source, bears an internal gear 1S which meshes with and drives the gears 15 on shafts l0, so as to cause the cylinders 9 to rotate in the same direction as said drive shaft, as indicated by tlie arrows Fig. 8. The drive shaft 17 extends longitudinally through substan` `tially the middle of the delinting chamber 1Q, and is arranged to extend substantially horizontal and parallel to the shafts 10, be- 1 ing journaled in bearings 19 which are bolted or otherwise secured to the heads 4. inlet spout Q0 communicates with one end of the delinting chamber l2 'through an opening 21 in the head el at one end of the maichiiie, and a discharge spout 2.', communieates with the other end of the delinting chamber 12 through an opening 23 in the other head il, said openings il and 23 being surrounded by flanges Q4 borne by said heads il. rEhe shaft 17 extends through the inlet spout 2O and bears an ir'irchiinedcan screw 25 or the like, which is adapted to rotate with said shaft, in order to feed the seeds from said spout 2O into the delinting chamber .l2 through the opening 20. Said shaft 17 extends, also7 through the discharge spout 22 and has a valve 26 reciproeatively mounted thereon for the purpose of controlling the passage of the delinted seeds through the opening 23 from the delinting chamber 12 into the discharge spout 22, said valve being preferably (hek-shaped and being substantially the same size and having the same .shape as the opening 23.

A. sleeve 27 borne by valve 2G encircles shaft 17 and contains a screw-threaded opening to receive a bolt or screw 28. Said bolt or screw 28 is preferably screw-threaded only along a portion of its length, in order to lit in the screw-threaded opening in sleeve 27, and the end portion of said bolt or screw is left smooth and extends through an elongated slot 29 in shaft 17, which slot communicates with an opening' 30 that extends longitudinally in the end of said shaft 17. The end of the bolt or screw 28 projects from the slotl 29 into an opening in. valve-stem 31, which is located in the opening 30 in shaft 17 and is capable of reciprocating therein. By reason of valve 26 and its stem 31 being connected by the bolt or screw 28, as just described, same are caused to rotate with shaft 17, and whenever the valve 26 is moved longitudinally on shaft 17, the bolt or screw 28 causes the stem 81 to move with said valve, or vice versa. The stem 31 extends from the end of shaft 17 and the end thereof bears against the end of a screw-threaded rod 32, which passes through a screw-threaded opening in bracket 38, said bracket being secured to one of the bearings 19 by a set-screw 311 or other suitable means, and said rod having a hand-wheel secured thereto to afford a means for turning same. The seeds within the delinting chamber 12 press against the face of valve 26 and thereby tend to move said valve away from the opening 23, in order to allow the delinted seeds to pass from the delinting chamber 12 into the discharge spout 22. Such movement of valve 2G is limited by the engagement of its stem 31 with the end of rod 32, and by means of said rod the valve 2G can be adjusted with respect to the opening 23, in order to allow the delinted seeds to discharge faster .or slower from the delinting chamber 12, as may be desired. Said discharge spout 22 is provided with a sight-hole 3G through which the interior of said spout can be observed from outside the machine. The delinted seeds discharge from the spout 22 into a suitable receptacle or conveying means (not shown).

' A, cylinder 37, which is preferably formed of a metal tube, is rigidly mounted on the drive shaft 17 by means of heads 3S, and extends substantially from one end of the delinting chamber 12 to the other end thereof. Said cylinder 37 is relatively smaller in diameter than the cylinders 9 and is, also, screw-threaded externally and the periphery of the screw-threads is serrated so as to form teeth 14: which are adapted to remove the lint or fibers from the seeds that come in contact with said cylinder.

The screw-threads on cylinder 37 are, also, formed with a relatively large pitch, and slant in the same direction as the screwthreads on the cylinders 9. By this arrangement, as the cylinder 37 rotates in the same direction as the cylinders 9, the screwthreads on the former, also, have a tendency to feed the seeds from the receiving end to the discharge cnd of the delinting chamber.

While it is preferable to drive the cylinders 9 in the same direction as the cylinder 37 by means of the internal gear 18, yet it should be understood that said cylinders 9 may be driven in the opposite direction from the cylinder 37 as in my above-mentio-ned companion application, in which event, the screw-threads on cylinder 37 may slant in the opposite direction from the screw-threads on cylinders 9, so that the screw-threads on said cylinders 9 and 37 have a tendency to move the seeds through the delinting chamber.

The staves 11 are located between the cylinders 9, in order to retain the seeds in the delinting chamber 12, one of said staves being arranged to close the top, another to close t-he bottom, and the others to close the sides of said delinting chamber, being preferably spaced at substantially equal distances from said cylinder 37. Each stave 11 is preferably formed of a plate which may he secured to a bar 39 by any suitable means, or, if desired, may be formed integrally with said bar. Said bar 39 extends from end to end of the machine, and has its ends supported and held firmly in pillow-blocks 40 supported by heads et, as described and illustrated in my above-inentioned companion application, so that same can be readily adjusted. A blade 41, which extends longitudinally of stave 11, is preferably riveted or otherwise secured to the inner face of said stave, e'. c., the face that is exposed to the delinting chamber 12, and a plate e2, which, also, extends longitudinally of said stave, is detachably and adjustably secured to the outer face of said stave by any suitable means (not shown) so that same can be adjusted transversely of said plate 42. Each stave 11 occupies an inclined position, and is so adjusted that the beveled edge of its blade i1 nearly touches the teeth 1st on an adjacent delinting cylinder 9, so as to deflect the seeds from said cylinder, and its plate 4t2 is adjusted so that an edge thereof nearly touches the teeth 14 of another cylinder 9 adjacent thereto, in order to prevent the seeds from falling out of the chamber 12, said cylinders 9 being rotated so that the cylinder 9 adjacent the blade 11 moves the seeds toward said blade, and the cylinder adjacent. the plate 42 mores the seeds away from said plate.

X shartt d3 is n'eterably arranged to oxtend lroin end to end et the machine and is jonrnaleil in a bearing /l/l' borne by one oit the heads el and, also in a brat-,kot 45, which is bolted or otherwise secured to the other head 4f, being located above the upper' stave ll and having a member 4G or a plurality of such members mounted thereon so as to rotate therewith. Each member t6 is provided with plurality of arms 1li' to which the blades or plates t8 are riveted or otherwise secured. A pulley l-9 borne by drive shaft 17 drives a belt 50, which, in turn, drives a pulley 5l rigidly mounted on shaft 4:8, thereby rotating said shaft 43, and causing` the blades L18 to tan or blow the lint away trom the upper stave ll. By this arrangement, the lint is prevented from accumulating on top of the upper stave ll, in the space between the upper cylinders 9. 'lhe operation ot the machine is as tollows: Power is applied to the drive shaft 17 from any suitable source, so as to cause the cylinder 37 to rotate therewith and, also, to rotate the cylinders 9 through the intermediation ot' gears l5 and 18. The seeds to be delinted are ted into the receiving spout 2O and are then caused by the pressure ot screw Q5 to pass through the opening 2l into the delinting chamber l2 and to travel toward the valve 26, so as to till the space around the cylinder 37. The teeth let borne by the cylinders 9 and 37 not only remove the lint and liber trom the seeds, but, also, agitate the seeds within the chamber l2, with the result that, while the seeds are being ted through the delinting chamber l2 by the screw Q5, the agitation ot the seeds by the cylinders 9 and Si", cause each s-eed to come in contact with one o1 more oll the cylinders 9 or with the cylinder 87, thus retrieving all the short libers or lint from each seed that passes through the delinting chamber. The pressure ot the seeds within the delinting chamber 1Q holds the valve QG o1 en and thereby allows the delinted seeds to escape from said delinting chamber into the discharge spout rl`he lint or liber that is scraped oit the seeds by the teeth lll on the delinting cylinders 9 drops from said cylinders into the bottom oit the casing. and is then drawn away through the suction-pipe 8. The suction trom pipe 8 causes the lint that is scraped off the seeds by the teeth let on the cylinder 3T to escape from the delinting chamber i2 into the bottom et' the casing l and then to discharge through the suction-pipe S.
